(3)When any public road or part thereof is permanently closed, the Board at a meeting may sell or lease the site of so much of the road way as is no longer required, making due compensation to, or providing means of access for, any person who may suffer damage by such closing. In determining such compensation, allowance shall be made for any benefit accruing to the same premises or any adjacent premises belonging to the same owner from the construction or improvement of any other public road at or about the same time that the public road on account of which the compensation is paid, is closed. Provided that the Board cannot sell or otherwise dispose of the site if it is vested in the Board under Section 62 and is not of the nature specified at Section 63.
